51043240 ÷ 14 
We want to divide 51043240 by 14.

Let's proceed to step 1:
14 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 14

On to step 2:
If we divide 51 by 14, we get 3 and a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 42 from 51 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 14

Advancing to step 3:
14 goes into 90 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 36.0
Deduct 84 from 90 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 14

Moving on to step 4:
14 goes into 64 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 364.0
Deduct 56 from 64 and we're left with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 14

Going ahead to step 5:
When dividing 83 by 14, we get 5 with a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 3645.0
Subtracting 70 from 83 leaves us with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 14

Let's proceed to step 6:
If we divide 132 by 14, we get 9 and a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 36459.0
If we take 126 away from 132, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 14

Let's proceed to step 7:
If we divide 64 by 14, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 364594.0
The remainder is 8 after subtracting 56 from 64.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 14

Going ahead to step 8:
When dividing 80 by 14, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3645945.0
The remainder is 10 after subtracting 70 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
The number 14 fits into 100 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 3645945.7
If we subtract 98 from 100, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
14 can be fit into 20 1 times, resulting in a remainder of 6.
The next digit of our result is 1. 
Result so far: 3645945.71
If we subtract 14 from 20, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
60 divided by 14 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 3645945.714
Deduct 56 from 60 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
If we divide 40 by 14, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 3645945.7142
If we take 28 away from 40, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
120 divided by 14 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 3645945.71428
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
The number 14 fits into 80 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3645945.714285
Deduct 70 from 80 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 15:
If we divide 100 by 14, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 3645945.7142857
Subtract 98 from 100 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 16:
14 goes into 20 1 times with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 3645945.71428571
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 3645945.71428571 with a balance of 6e-09.
